The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless otherwise specified.

In the description of the present application, it is to be noted that the terms "mounted," "connected," and "connected" are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected unless otherwise explicitly stated or limited. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

The terms referred to in this application are explained first:

ultrasonic vibration plate: the high-frequency oscillation signal emitted by an ultrasonic generator is converted into high-frequency mechanical oscillation by a transducer and is transmitted to a medium, ultrasonic waves are radiated forwards at intervals in a cleaning liquid to make the liquid flow to generate tens of thousands of micro-bubbles, the micro-bubbles (cavitation nuclei) in the liquid vibrate under the action of a sound field, when sound pressure reaches a certain value, the bubbles rapidly grow and then are suddenly closed, shock waves are generated when the bubbles are closed, thousands of atmospheric pressures are generated around the bubbles, insoluble dirt is damaged to disperse the micro-bubbles in the cleaning liquid, when group particles are wrapped by oil dirt and adhered to the surface of a cleaning piece, the oil is emulsified, and solid particles are separated, so that the purpose of cleaning the surface of the cleaning piece is achieved.

Cavitation: the micro-gas core cavitation bubbles in the liquid vibrate under the action of sound waves, and the dynamic process of growth and collapse occurs when the sound pressure reaches a certain value. When ultrasonic wave acts on liquid, a large number of small bubbles can be generated, one reason is that a tensile stress locally appears in the liquid to form a negative pressure, and the pressure is reduced to enable the gas originally dissolved in the liquid to be supersaturated and to escape from the liquid to be small bubbles. Another reason is that strong tensile stresses "tear" the liquid into a void, known as cavitation.

Conical surface holes: the circular hole with the side wall being a conical surface is a circular hole, particularly a circular hole which is formed by rotating a right-angle trapezoid around a right-angle edge of the circular hole to form a rotation space, and the space is complementary with a circular truncated cone. The round table is a solid body, and the conical surface hole is a space.

An embodiment of the present application provides a small-sized cleaning apparatus for electroplated workpieces, as shown in fig. 1 and 2, comprising a cleaning tank housing 1 for containing a cleaning solution and a containing frame 2 disposed in the cleaning tank housing 1.

The shape of the flange 21 is not limited, and the horizontal flange 21 is taken as an example in fig. 2, and in other embodiments, the L-shaped flange may be clamped with the top end of the side wall and the outside of the side wall of the cleaning tank shell. The lateral wall and the bottom that hold frame 2 evenly set up a plurality of through-holes 22 that supply the washing liquid circulation, through-hole 22 is big-end-up interior little conical surface hole, and through-hole 22 cross section is circular convenient processing. The diameter of the through hole 22 at one end of the inner side of the containing frame 2 is smaller than the size of the workpiece, so that the workpiece is prevented from scattering outside the containing frame 2. An ultrasonic vibration plate 3 which drives the cleaning liquid to vibrate is arranged in the cleaning tank shell 1.

If the small-size work piece that holds in the plating basket is more, the small-size work piece vibration back of top layer scatters outside to plating the basket, falls on holding in frame 2, because the size of the through-hole that holds 2 inner walls of frame is less than the size of small-size work piece, small-size work piece can not scatter to hold frame 2 outside and mix with impurity. In addition, the through hole 22 can be with leading-in the frame 2 that holds of bubble that ultrasonic cavitation produced concentratedly, under the same condition of ultrasonic power source, the bubble is concentrated from the through hole 22 and is gushed to holding frame 2 inboard, a plurality of bubbles extrude each other and can increase the pressure that holds the interior bubble of frame 2, the closed shock wave that produces of bubble is stronger after the pressurized bubble reaches the small-size work piece surface that holds frame 2 inboard, destroy small-size work piece surface's greasy dirt and impurity, greasy dirt and impurity scatter to the cleaning solution in then sink and reach abluent effect, the pressurization can strengthen the cleaning performance. In addition, the size of the through hole 22 on the outer wall of the containing frame 2 is larger than the size of the through hole 22 on the inner wall of the containing frame 2, and in the process that bubbles enter the inner side from the outer side of the containing frame 2, the sectional area of the through hole 22 is gradually reduced, under the condition that the initial flow provided by the ultrasonic power source is the same, the flow rate of the bubbles is gradually increased, when the liquid pressure is smaller than the saturated steam pressure, the bubbles in the cleaning liquid are continuously expanded, the volume is increased, and after the bubbles enter the plating basket in the containing frame 2 through the through hole 22, the bubbles reach a relatively low flow rate area, and then the bubbles are more violently collapsed and burst.
